It is beyond ridiculous for anyone to pretend that the border can ever be secured without may miles of double fencing and adequate.
Perry's babbling about enforcing the border with manpower is absurd because the government will never keep adequate BP or troops on the border 24/7/365.
Perry and Juan McCain are the same on the border: pretend to be for border enforcement and plan for amnesty at some later date.
Screw the fence, Put troops on border with live ammo and very liberal rules of engagement. Illegal immigrant flood will become a trickle.
